Question 5

A 3-month-old client is in the pediatric unit. During assessment, the nurse is suspecting that the baby may have hypothyroidism when mother states that her baby does not:

A

Sit up.

B

Pick up and hold a rattle.

C

Roll over.

D

Hold the head up.

Question 5 Explanation:

Development normally proceeds cephalocaudally; so the first major developmental milestone that the infant achieves is the ability to hold the head up within the first 8-12 weeks of life. In hypothyroidism, the infant’s muscle tone would be poor and the infant would not be able to achieve this milestone.

Question 6

Radioactive Iodine's main function in therapy is to:

A

Rapidly inhibits the synthesis/release of T3 & T4

B

Blocks conversion of T4 to T3

C

Damages or destroys thyroid tissue

D

Decreases HR, BP, CO2, and O2 requirements

Question 7

A client has been newly diagnosed with hypothyroidism and will take levothyroxine (Synthroid) 50 mcg/day by mouth. As part of the teaching plan, the nurse emphasizes that this medication:

A

Should be taken in the morning

B

May decrease the client’s energy level

C

Must be stored in a dark container

D

Will decrease the client’s heart rate

Question 7 Explanation:

Should be taken in the morning Thyroid supplement should be taken in the morning to minimize the side effects of insomnia

Question 8

A client is admitted with a diagnosis of hypothyroidism. An initial assessment of the client would reveal:

On discharge, the nurse teaches the patient to observe for signs of surgically induced hypothyroidism. The nurse would know that the patient understands the teaching when she states she should notify the MD if she develops:

A

Intolerance to heat

B

Dry skin and fatigue

C

Progressive weight gain

D

Insomnia and excitability

Question 9 Explanation:

Hypothyroidism, a decrease in thyroid hormone production, is characterized by hypometabolism that manifests itself with weight gain

Question 10

An incoherent female client with a history of hypothyroidism is brought to the emergency department by the rescue squad. Physical and laboratory findings reveal hypothermia, hypoventilation, respiratory acidosis, bradycardia, hypotension, and nonpitting edema of the face and pretibial area. Knowing that these findings suggest severe hypothyroidism, nurse Libby prepares to take emergency action to prevent the potential complication of:

A

Thyroid storm.

B

Cretinism.

C

myxedema coma.

D

Hashimoto’s thyroiditis.

Question 10 Explanation:

Severe hypothyroidism may result in myxedema coma, in which a drastic drop in the metabolic rate causes decreased vital signs, hypoventilation (possibly leading to respiratory acidosis), and nonpitting edema. Thyroid storm is an acute complication of hyperthyroidism. Cretinism is a form of hypothyroidism that occurs in infants. Hashimoto’s thyroiditis is a common chronic inflammatory disease of the thyroid gland in which autoimmune factors play a prominent role.

Question 11

High TSH but low FT4 suggests...
Hint: TSH and FT4 levels going in opposite directions is usually what we expect to see, generally indicating a problem on the level of the thyroid.

A

Primary hyperthyroidism

B

Primary hypothyroidism

C

Pituitary hyperthyroidism

D

Pituitary hypothyroidism

E

Hypothalamus hypothyroidism

Question 12

Which of the following potentially serious complications could occur with therapy for hypothyroidism?

A

Acute hemolytic reaction.

B

Angina or cardiac arrhythmia.

C

Retinopathy.

D

Thrombocytopenia.

Question 12 Explanation:

Precipitation of angina or cardiac arrhythmia is a potentially serious complication of hypothyroidism treatment. Acute hemolytic reaction is a complication of blood transfusions. Retinopathy typically is a complication of diabetes mellitus. Thrombocytopenia doesn’t result from treating hypothyroidism.

Question 13

A nurse gets back results on a pt who may have hypothyroidism. What lab values might the nurse expect?

A

decreased T3 and Increased T4

B

increased TSH and Increased T3 and T4

C

Increased TSH and decreased T3 and T4

D

Increased T3 and Decreased T4

Question 14

A client with hypothyroidism asks the nurse if she will still need to take thyroid medication during the pregnancy. The nurse’s response is based on the knowledge that:

A

There is no need to take thyroid medication because the fetus’s thyroid produces a thyroid-stimulating hormone.

B

Regulation of thyroid medication is more difficult because the thyroid gland increases in size during pregnancy.

C

It is more difficult to maintain thyroid regulation during pregnancy due to a slowing of metabolism.

D

Fetal growth is arrested if thyroid medication is continued during pregnancy.

Question 14 Explanation:

During pregnancy, the thyroid gland triples in size. This makes it more difficult to regulate thyroid medication.

Levothyroxine, a synthetic thyroid hormone, is given to a client with hypothyroidism to simulate the effects of thyroxine. Adverse effects of this agent include tachycardia. The other options aren’t associated with levothyroxine.

Question 19

Iodine's main function in therapy is to:

A

Rapidly inhibits the synthesis/release of T3 & T4

B

Blocks conversion of T4 to T3

C

Damages or destroys thyroid tissue

D

Decreases HR, BP, CO2, and O2 requirements

Question 20

A

Follicle

B

Squamous

C

Epithelial

D

Glandular

A

Grave's

B

Hashimoto's

C

Silent thyroiditis

D

Hypothalamic disease

E

Hypermetabolism from decrease in T3 and T4.

B

Hypometabolism from decrease in T3 and T4.

C

Hypermetabolism from increase in T3 and T4.

D

Hypometabolism from increase in T3 and T4.

Question 29

Mrs. Gilmour is complaining of being hot all the time, sweating, being thirsty, and losing hair. What could her symptoms indicate?

Levothyroxine is the preferred agent to treat primary hypothyroidism and cretinism, although it also may be used to treat secondary hypothyroidism. It is contraindicated in Graves’ disease and thyrotoxicosis because these conditions are forms of hyperthyroidism. Euthyroidism, a term used to describe normal thyroid function, wouldn’t require any thyroid preparation.
